/**
 * A JSONObject is an unordered collection of name/value pairs. Its external
 * form is a string wrapped in curly braces with colons between the names and
 * values, and commas between the values and names. The internal form is an
 * object having <code>get</code> and <code>opt</code> methods for accessing the
 * values by name, and <code>put</code> methods for adding or replacing values
 * by name. The values can be any of these types: <code>Boolean</code>,
 * <code>JSONArray</code>, <code>JSONObject</code>, <code>Number</code>,
 * <code>String</code>, or the <code>JSONObject.NULL</code> object. A JSONObject
 * constructor can be used to convert an external form JSON text into an
 * internal form whose values can be retrieved with the <code>get</code> and
 * <code>opt</code> methods, or to convert values into a JSON text using the
 * <code>put</code> and <code>toString</code> methods. A <code>get</code> method
 * returns a value if one can be found, and throws an exception if one cannot be
 * found. An <code>opt</code> method returns a default value instead of throwing
 * an exception, and so is useful for obtaining optional values.
 * <p>
 * The generic <code>get()</code> and <code>opt()</code> methods return an
 * object, which you can cast or query for type. There are also typed
 * <code>get</code> and <code>opt</code> methods that do type checking and type
 * coersion for you.
 * <p>
 * The <code>put</code> methods adds values to an object. For example,
 * 
 * <pre>
 * myString = new JSONObject().put(&quot;JSON&quot;, &quot;Hello, World!&quot;).toString();
 * </pre>
 * 
 * produces the string <code>{"JSON": "Hello, World"}</code>.
 * <p>
 * The texts produced by the <code>toString</code> methods strictly conform to
 * the JSON sysntax rules. The constructors are more forgiving in the texts they
 * will accept:
 * <ul>
 * <li>An extra <code>,</code>&nbsp;<small>(comma)</small> may appear just
 * before the closing brace.</li>
 * <li>Strings may be quoted with <code>'</code>&nbsp;<small>(single
 * quote)</small>.</li>
 * <li>Strings do not need to be quoted at all if they do not begin with a quote
 * or single quote, and if they do not contain leading or trailing spaces, and
 * if they do not contain any of these characters:
 * <code>{ } [ ] / \ : , = ; #</code> and if they do not look like numbers and
 * if they are not the reserved words <code>true</code>, <code>false</code>, or
 * <code>null</code>.</li>
 * <li>Keys can be followed by <code>=</code> or <code>=></code> as well as by
 * <code>:</code>.</li>
 * <li>Values can be followed by <code>;</code> <small>(semicolon)</small> as
 * well as by <code>,</code> <small>(comma)</small>.</li>
 * <li>Numbers may have the <code>0-</code> <small>(octal)</small> or
 * <code>0x-</code> <small>(hex)</small> prefix.</li>
 * <li>Comments written in the slashshlash, slashstar, and hash conventions will
 * be ignored.</li>
 * </ul>
